There are situations where you actually want/ need a clean, visible seam (e.g.
https://forum.allegorithmic.com/index.php/topic,24299.0.html ). The new seam padding in Painter 2018.1 undermines the possiblily to create very clean seams e.g. using the UV chunk fill tool on a mask. Where you would get an absolutely clean seam prior to version 2018 you now get a very fuzzy transition. This is very useful in some situations because seams are hidden, while being very counter-productive in other situations where a clean, visible seam is actually wanted.
There should be the option to turn the new padding off.
